Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Next, referring to fig. 1 to 7, a single-track switch 201 according to an embodiment of the first aspect of the present invention is described.

As shown in fig. 1 and 2, a single-track switch 201 according to an embodiment of the present invention may include: a walking beam 2, a first mechanism 3 and a second mechanism 4. The number of the movable beams 2 included in each single-rail turnout 201 is not limited, and the type of the movable beam 2 is not limited, and the movable beam 2 may be an inner guide type rail beam or an outer guide type rail beam, and the shape of the movable beam 2 is not limited, and may be a curved beam or a linear beam.

With reference to fig. 3 and 4, the movable beam 2 is used to connect two fixed beams 1, two ends of the movable beam 2 are respectively a first end 21 and a second end 22, the first mechanism 3 is used to make the first end 21 of the movable beam 2 rotate and slide along a straight track, and the second mechanism 4 is used to make the second end 22 of the movable beam 2 rotate and slide along an arc track.

Wherein, the first end 21 of walking beam 2 rotates along the straight line orbit and slides, specifically is: the first end 21 of the movable beam 2 slides along a linear track while rotating. Moreover, it should be noted that the first mechanism 3 can only ensure that the first end 21 of the movable beam 2 rotationally slides along the linear track, but cannot drive the first end 21 of the movable beam 2 to rotationally slide along the linear track. It should be noted that the straight trajectory is not perpendicular to the fixed beam 1 (for example, the first fixed beam 1a shown in fig. 4) for engaging with the first end 21 of the mobile beam 2, so as to ensure the effectiveness of the switch switching.

Wherein, the second end 22 of walking beam 2 rotates along the pitch arc orbit and slides, specifically is: the second end 22 of the walking beam 2 rotates and slides along an arc track. Moreover, it should be noted that the second mechanism 4 can only ensure that the second end 22 of the movable beam 2 rotationally slides along the arc track, but cannot drive the second end 22 of the movable beam 2 to rotationally slide along the arc track.

Thus, the first mechanism 3 may correspond to a slider mechanism in a crank slider mechanism, the second mechanism 4 may correspond to a crank mechanism in a crank slider mechanism, and the movable beam 2 may move to achieve movement between a first position (e.g., a position of the first fixed beam 2a, a position of the second fixed beam 2b 'shown in fig. 4) where the two fixed beams 1 are engaged and a second position (e.g., a position of the first fixed beam 2 a', a position of the second fixed beam 2b shown in fig. 4) where the two fixed beams 1 are not engaged, thereby achieving switching.

Therefore, the monorail switch 201 according to the embodiment of the invention has the advantages of simple structure, convenient processing, low cost, and capability of simply, quickly and effectively realizing switch switching. Moreover, the movable beam 2 can be a rigid beam body, so that the manufacturing difficulty is low, the cost is low, the rigidity is high, multiple supports are not needed, and a damping system is not needed, so that the single-rail turnout 201 is simple in overall structure, low in cost and good in reliability.

In some embodiments of the invention, as shown in fig. 3, the first mechanism 3 may comprise: the first trolley 31 is hinged to the first end 21 of the movable beam 2, and the linear guide rail 32 is in sliding fit with the first trolley 31, so that the first trolley 31 slides along a linear track relative to the linear guide rail 32. The longitudinal direction of the linear trajectory is the longitudinal direction of the linear guide rail 32. In this way, when the first carriage 31 slides along a linear track with respect to the linear guide rail 32, the first carriage 31 can rotate with respect to the first end 21 of the movable beam 2, and the first end 21 of the movable beam 2 can be rotated and slid along the linear track. Therefore, the first mechanism 3 has a simple structure, is convenient to process, and can simply and effectively realize the rotating and sliding of the first end 21 of the movable beam 2 along a straight track.

In addition, there are many ways for the linear guide rail 32 to slidably fit with the first trolley 31, for example, referring to fig. 7, a rail strip 321 extending along a straight line may be provided on the linear guide rail 32, a rail groove 311 may be provided on the first trolley 31, and the rail strip 321 is inserted into the rail groove 311, so that the first trolley 31 may slidably move along a straight track, where an extending direction of the rail strip 321 is a length direction of the linear guide rail 32, and a length of the rail strip 321 may be equal to a length of the linear guide rail 32. Or in other examples of the present invention, the first carriage 31 has a rail block thereon, the linear guide rail 32 has a rail channel extending along a straight line, and the rail block is embedded in the rail channel so that the first carriage 31 can slide along a straight track.

Furthermore, as shown in fig. 5, the first trolley 31 is not limited to be hinged to the first end 21 of the movable beam 2, and for example, the first trolley 31 and the first end 21 of the movable beam 2 may be connected by the pivot bearing 7, so that the first end 21 of the movable beam 2 is rotatable relative to the first trolley 31 about a vertical axis passing through the first end 21 of the movable beam 2.

In some embodiments of the present invention, as shown in fig. 5, the monorail switch 201 may further include a driving mechanism 5, and the driving mechanism 5 is configured to drive the first end 21 of the movable beam 2 to slide along a linear track, so that, by providing the driving mechanism 5, switching is achieved without manual pushing, thereby reducing manual labor, improving convenience of switching, and improving switching efficiency. In addition, when the driving mechanism 5 is configured to drive the first end 21 to slide along a straight line, the structural complexity of the driving mechanism 5 can be simplified, the production cost can be reduced, and the driving resistance and the driving friction can be reduced to a certain extent.

Of course, the invention is not limited thereto, and in other embodiments of the invention, the driving means may also be arranged for driving the second end 22 of the travelling beam 2 to glide along an arc trajectory, whereby a switch may be effected as well. In addition, in other embodiments of the present invention, switching may also be implemented by manual pushing. For simplicity of description, the following description will be given only by way of example of the driving mechanism 5 configured to drive the first end 21 of the walking beam 2 to slide along a linear track, and it is obvious that the driving mechanism 5 is another embodiment after reading the following technical solutions.

In some embodiments of the present invention, as shown in fig. 5, the driving mechanism 5 may include a driving motor 51 and a transmission assembly 52, and the driving motor 51 drives the first end 21 of the movable beam 2 to slide along a linear track through the transmission assembly 52. Therefore, the movable beam 2 can be driven to move in an electric control mode, and therefore the movable beam is easy to realize, convenient to control, high in safety and high in universality. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the driving mechanism 5 may also be driven by hydraulic driving, pneumatic driving, and the like, which are not described herein.

For example, in one specific example of the present invention, as shown in fig. 5, when the first mechanism 3 includes a first trolley 31 and a linear guide rail 32, the first trolley 31 is hinged to the first end 21 of the movable beam 2, and the linear guide rail 32 is slidably engaged with the first trolley 31, so that the first trolley 31 slides along a linear track relative to the linear guide rail 32, the transmission assembly 52 may be a rack-and-pinion transmission assembly and include a rack 521 and a pinion 522, the drive motor 51 drives the pinion 522 to move along the rack 521, the drive motor 51 and the pinion 522 are both disposed on the first trolley 31, and the rack 521 is disposed on the linear guide rail 32 and extends along the length direction of the linear guide rail 32. Therefore, the transmission assembly 52 has the advantages of simple structure, convenient processing and control, high action reliability, small driving friction and small driving resistance. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the transmission assembly 52 may also be a worm and gear assembly, a scissor assembly, an electric cylinder assembly, and so on, which are not described herein. Note that the longitudinal direction of the linear path herein is also the longitudinal direction of the linear guide 32, and the extending direction of the rack 521 is parallel to the linear path.

In some embodiments of the invention, as shown in fig. 3 and 6, the second mechanism 4 may comprise: a pivoting seat 41 and a rotating rod 42, wherein the pivoting seat 41 is stationary relative to the fixed beam 1, the rotating rod 42 is rotatably engaged with the pivoting seat 41, the rotating rod 42 has a hinge portion 421, and the hinge portion 421 is hinged to the second end 22 of the movable beam 2. Thus, when the rotating rod 42 rotates relative to the rotating seat 41, the hinge portion 421 on the rotating rod 42 can slide along an arc track, and the hinge portion 421 can rotate relative to the second end 22 of the movable beam 2, so that the second end 22 of the movable beam 2 can rotate and slide along the arc track. Therefore, the second mechanism 4 has a simple structure, is convenient to process, and can simply and effectively realize the rotating and sliding of the second end 22 of the movable beam 2 along the arc track.

In addition, there are many ways to rotatably couple the rotating rod 42 and the pivot seat 41, for example, the rotating rod 42 may have a pivot shaft or a pivot hole, and the pivot seat 41 may have a pivot hole or a pivot shaft, which extends vertically and is inserted into the pivot shaft, so that the rotating rod 42 can rotate around the pivot seat 41. Furthermore, the manner of hinging the hinge 421 with the walking beam 2 is not limited, for example, the hinge 421 and the walking beam 2 can be connected by a pivoting support 7, so that the second end 22 of the walking beam 2 can be rotated relative to the hinge 421 about a vertical axis passing through the second end 22 of the walking beam 2.

In some embodiments of the present invention, as shown in fig. 6, the second mechanism 4 may further comprise: and a second carriage 43, wherein the second carriage 43 is mounted on the bottom of the hinge portion 421. This reduces the load on the hinge portion 421 of the pivot lever 42, improves the pivoting flexibility of the pivot lever 42, improves the reliability of supporting the pivot lever 42 on the second end 22 of the movable beam 2, and improves the smoothness of movement of the second end 22 of the movable beam 2. In some specific examples, the bottom of the second trolley 43 may have a roller 431, so that the flexibility of the rotation of the rotating rod 42 may be further improved, the smoothness of the movement of the second end 22 of the movable beam 2 may be further improved, the switching friction may be reduced, the switching efficiency may be improved, and the switching driving force may be reduced. In addition, to facilitate the installation of the second carriage 43, the second carriage 43 may be further installed to the second end 22 of the movable beam 2 through two installation lugs 432.

In some embodiments of the present invention, as shown in fig. 7, the single-track switch 201 may further include: the locking mechanism 6, the locking mechanism 6 is used for locking the position of the movable beam 2, that is, the first end 21 of the movable beam 2 can be restricted from sliding along a straight track by the locking mechanism 6, and the second end 22 of the movable beam 2 can be restricted from sliding along an arc track. Therefore, the reliability of switch switching can be improved, and the passing safety and stability of the monorail track 200 are improved.

For example, in one specific example of the present invention, as shown in fig. 7, the locking mechanism 6 may be configured to lock the position of the first end 21 of the movable beam 2. In this way, by locking the position of the first end 21 of the movable beam 2, i.e., restricting the first end 21 of the movable beam 2 from moving along a linear trajectory, the second end 22 of the movable beam 2 can be restricted from moving along an arcuate trajectory, and the position of the movable beam 2 can be simply and efficiently locked. This reduces the difficulty of installing the lock mechanisms 6, reduces the number of lock mechanisms 6, and reduces the overall cost of the single-track switch 201. Of course, the invention is not limited thereto, for example in other embodiments of the invention, it is also possible to arrange a locking mechanism 6 for locking the position of the second end 22 of the walking beam 2.

In some specific examples of the present invention, as shown in fig. 7, when the first mechanism 3 includes a first carriage 31 and a linear guide 32, the linear guide 32 is slidably engaged with the first carriage 31 so that the first carriage 31 slides along a linear track with respect to the linear guide 32. At this time, the lock mechanism 6 may be provided on the first carriage 31 and used to lock the first carriage 31 to the linear guide 32. This makes the lock mechanism 6 simple to mount and highly reliable in operation.

As shown in fig. 7, the first carriage 31 may be formed with the track groove 311, and the linear guide 32 may be formed with the track bar 321 inserted into the track groove 311, and in this case, the lock mechanism 6 may be provided on the first carriage 31 and may include: the clamp arm 61, locking piece 62 and unblock piece 63, the clamp arm 61 is two and distributes in the width both sides of track strip 321, and locking piece 62 is used for driving two clamp arms 61 and presss from both sides tight track strip 321, and unblock piece 63 is used for driving two clamp arms 61 and release track strip 321. This simplifies the structure of the lock mechanism 6 and improves the operational reliability.

For example, in the specific example shown in fig. 7, the caliper arms 61 are rotatably provided on the first carriage 31 so as to be rotatable about a lateral axis parallel to the lateral shaft portion 611 of the rail bar 321, the rail bar 321 is provided between the lower ends of the two caliper arms 61, the unlocking member 63 serves to drive the upper ends of the two caliper arms 61 closer together to separate the lower ends of the two caliper arms 61 to release the rail bar 321, and the locking member 62 serves to drive the upper ends of the two caliper arms 61 apart to bring the lower ends of the two caliper arms 61 closer together to clamp the rail bar 321. Thus, by controlling the reverse rotation of the caliper arm 61 by the locking piece 62 and the unlocking piece 63, the locking and unlocking can be switched simply and efficiently. Therefore, the caliper arm 61 has high operation reliability and is convenient to process and assemble.

Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the caliper arm 61 may also be locked and unlocked by translation or the like. In addition, it should be noted that in the description of the present invention, it is to be understood that the terms "upper", "lower", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention. For example, when the single-track switch 201 is used upside down, such as for a track transportation system 1000 with the train 100 down and the single-track 200 up, the "up" direction described herein is exactly the actual "down" direction, whereas when the single-track switch 201 is used upright, such as for a transportation system with the train 100 up and the single-track 200 down, the "up" direction described herein is exactly the actual "up" direction.

As above, when the clamp arms 61 are rotatably provided on the first carriage 31, the locking member 62 may be provided between the upper ends of the two clamp arms 61 and include the return spring 621, that is, the return spring 621 normally drives the upper ends of the two clamp arms 61 apart to bring the lower ends of the two clamp arms 61 closer to each other to clamp the rail bar 321, and after the return spring 621 is compressed, the upper ends of the two clamp arms 61 may be brought closer to each other to bring the lower ends of the two clamp arms 61 apart to release the rail bar 321. Thus, the lock member 62 has a simple structure, low cost, and high operational reliability.

As above, when the clamp arm 61 is rotatably provided on the first carriage 31, the unlocking member 63 may be provided between the upper ends of the two clamp arms 61 and include two moving irons 631 and an electromagnet 632 located between the two moving irons 631, the two moving irons 631 being provided on the two clamp arms 61, respectively, the electromagnet 632 being configured to attract the two moving irons 631 closer by being energized. That is, the electromagnet 632 does not attract the two movable irons 631 to approach when the electromagnet 632 is powered off, at this time, the upper ends of the two clamp arms 61 can be separated by the locking member 62, so that the lower ends of the two clamp arms 61 approach to clamp the track bar 321, and after the electromagnet 632 is powered on, the two movable irons 631 are attracted to approach the electromagnet 632, at this time, the upper ends of the two clamp arms 61 can approach to separate the lower ends of the two clamp arms 61 to release the track bar 321. Thus, the unlocking member 63 has a simple structure, low cost, and high operation reliability.

At this time, the locking mechanism 6 may be an electric band-type mechanism, and the position locking of the movable beam 2 may be simply and effectively controlled in an electric control manner, and when the driving mechanism 5 is also an electric driving mechanism, the locking mechanism 6 and the driving mechanism 5 may be integrally controlled electrically, so that the switch switching is more conveniently realized, and the reliability of the switch switching action is improved. Of course, the present invention is not limited thereto, for example, in other embodiments of the present invention, the locking mechanism 6 may also be a latch type locking mechanism, a flap type locking mechanism, etc. in the related art, which will not be described herein.

In addition, the end of the caliper arm 61 (e.g., the lower end as shown) that is used to clamp the rail bar 321 may be provided with a brake pad 64 to improve the service life and locking reliability of the locking mechanism 6. Of course, in order to better improve the service life and locking reliability of the locking mechanism 6, the brake pads 64 may be provided in a replaceable form, i.e., the brake pads 64 may be detachably connected to the caliper arm 61.

Specifically, the number of the movable beams 2 included in the monorail turnout 201 according to the embodiment of the invention is not limited, and depends on the number of the switching tracks required for switching the monorail track 200, for example, when the monorail turnout 201 according to the embodiment of the invention is a single turnout or a split turnout, the movable beams 2 may be two, and for example, when the monorail turnout 201 according to the embodiment of the invention is a single turnout or another multiple turnout, the movable beams 2 may be three or more than three. For simplicity of description, the single-track switch 201 of the embodiment of the present invention is described as a single-switch or a split-switch, and it is obvious that the single-track switch 201 is a specific implementation of other switch after the following technical solutions are read by those skilled in the art.

As shown in fig. 3-4, the fixed beam 1 may include a first fixed beam 1a, a second fixed beam 1b, and a third fixed beam 1c, and the number of the movable beams 2 may be two, where one movable beam 2 is used to connect the first fixed beam 1a and the second fixed beam 1b, and the other movable beam 2 is used to connect the first fixed beam 1a and the third fixed beam 1c, each movable beam 2 separately adopts one first mechanism 3, and the two movable beams 2 adopt the same second mechanism 4.

For the sake of clarity, two movable beams 2 are defined as a first movable beam 2a and a second movable beam 2b, wherein the first movable beam 2a is used for joining the first fixed beam 1a and the second fixed beam 1b, and the second movable beam 2b is used for joining the first fixed beam 1a and the third fixed beam 1 c.
